On some 2011-2015 Volt and 2014 ELR models, DTC P0335 (Crankshaft Position Sensor Circuit) and/or P0336 (Crankshaft Position Sensor Performance) may be stored in history in the T6 Power Inverter Module (Hybrid Powertrain Control Module, or HPCM).
If DTCs P0335 and/or P0336 are stored in history, check that ground locations G106 (engine block) (Below Figure - A) and G113 (drive unit case) (Below Figure - B) are clean and tight. On rare occasions, the bolt hole for G113 may not be drilled to the proper depth, which will cause the ground bolt to bottom out in the hole and result in low clamp load on the ground eyelet.
